Calculation of the intensity at the sharp focus of a cylindrical vector beam by three methods
Компьютерная оптика, 2023 We conduct a comparative analysis of diffraction fields upon sharply focusing vortex and non-vortex incident beams, calculated using three non-paraxial methods. The methods employed are a finite difference time domain (FDTD) method, a Rayleigh–Sommerfeld
